The great Commonwealth of Pennsylvania, also known as the "Keystone State," the loss of which, presumably, would send the Union into disarray not seen in more than 140 years, has -- believe it or not -- at least a few claims that rank it above many other states: Specifically, the "Do Not Call" law, which allows Pennsylvania residents to register with the state attorney general to block most unsolicited telephone calls.

Despite its seeming simplicity, this law is sheer genius. And it's working. Lawmakers in Pennsylvania, and other states that have adopted similar measures, deserve to be commended for enacting it into law.
